WARNING: To avoid water damage and/or scalding
due to valve operation, a discharge line must be
connected to valve outlet and run to a safe place of
disposal. The discharge line shall be installed to allow
complete drainage of both the valve and the discharge
line. No reducing coupling or other restriction shall be
installed in the discharge line. The discharge line must
pitch downward from the valve and terminate with a 6"
(152mm) air gap from an approved location or build-
ing drain. The discharge line must terminate through
plain (unthreaded) pipe. Discharge line material must
conform to local plumbing code or A.S.M.E. require-
ments. Excessive length - more than 30 feet (9.14m),
use of more than four elbows or bends in discharge
piping, or reduction of discharge line size will cause
a restriction and reduce the discharge capacity of the
valve. No shut-off valve shall be installed between the
relief valve and tank, or in the discharge line.
To ensure proper operation, this valve must be
installed by a qualified service technician or
licensed plumbing contractor in
accordance with these instructions and local
plumbing codes and standards.
WARNING:
FAILURE TO COMPLY WITH THESE INSTRUCTIONS
REGARDING THIS VALVE CAN RESULT IN SERIOUS
PERSONAL INJURY OR DEATH AND/OR SEVERE
PROPERTY DAMAGE.
Combination temperature and pressure relief
valves with extension thermostats must be in-
stalled so that the temperature-sensing element
is immersed in the water in the top 6" (152mm)
of the water storage tank. They must be installed
either in the hot outlet service line or directly in a
tank tapping. Valves must be located so as to as-
sure isolation from flue gas heat or other ambient
conditions that are not indicative of stored water
temperature. See other instructions regarding the
discharge line.
This device is designed for emergency safety relief
and must not be used as an operating control.
Repair or alteration of valve in any way is prohib-
ited by national safety standards/local codes.
DO NOT REMOVE THIS TAG FROM VALVE.
WARNING:
FAILURE TO COMPLY WITH THESE
INSTRUCTIONS REGARDING THIS VALVE CAN
RESULT IN SERIOUS PERSONAL INJURY OR DEATH
AND/OR SEVERE PROPERTY DAMAGE.
ANNUAL OPERATION OF T&P RELIEF VALVES
WARNING: Following installation, the valve lever
MUST be operated AT LEAST ONCE A YEAR by the wa-
ter heater user/consumer to ensure that waterways
are clear. Certain naturally occurring mineral deposits
may adhere to the valve, blocking waterways, render-
ing it inoperative. When the lever is operated, hot water
will discharge if the waterways are clear. PRECAUTIONS
MUST BE TAKEN TO AVOID PERSONAL INJURY FROM
CONTACT WITH HOT WATER AND TO AVOID PROPERTY
DAMAGE. BEFORE operating lever, check to see that a
discharge line is connected to this valve, directing the
flow of hot water from the valve to a proper place of
disposal. If water does not flow freely when the lever
is operated, replacement of the valve is required. TURN
THE WATER HEATER “OFF” (see instruction manual)
AND CALL A PLUMBER IMMEDIATELY.
REINSPECTION OF T & P RELIEF VALVES:
WARNING: Temperature and Pressure Relief Valves
should be inspected and replaced, if necessary, AT
LEAST ONCE EVERY TWO TO FOUR YEARS depend-
ing on local water conditions and the advice of a lo-
cal licensed plumber or qualified service technician.
If corrosion or scaling of the valve is evident, the
replacement of the valve and the valve’s installation
environment should be assessed. Certain naturally oc-
curring conditions may corrode the valve or its compo-
nents over time, rendering the valve inoperative. Such
conditions can only be detected if the valve and its
components are physically removed and inspected. Do
not attempt to conduct an inspection on your own.
Contact your plumbing contractor for a reinspection to
assure continuing safety.
WARNING: FAILURE TO
REINSPECT THIS VALVE AS DIRECTED COULD
RESULT IN UNSAFE TEMPERATURE OR PRESSURE
BUILD-UP WHICH CAN RESULT IN SERIOUS INJURY
OR DEATH AND/OR SEVERE PROPERTY DAMAGE.
If discharge occurs, CALL A PLUMBER IMMEDIATELY.
Discharge may indicate that an unsafe temperature or
pressure condition exists which requires immediate
attention by a qualified service technician or licensed
plumbing contractor.
